Must be true. As shown below, if we take the contrapositive of the conditional chain, we see that a truly visual art form does not require performance.

Could be false. We don’t have enough information to compare how similar these art forms are.

Could be false. The stimulus does not indicate that spatiality and temporality can never coexist in art.

Could be false. (D) introduces topics that are not included in the stimulus, like understanding (rather than experiencing) art and extended (rather than fixed) periods of time.

Could be false. We know that all performances must be experienced in a fixed order and over a roughly fixed amount of time, but we don’t know that all performances are either musical or poetic––music and poetry are just referenced as two possible examples of performance.
